The LM is a high-performance audio power amplifier capable of delivering 56W of continuous average power to an 8Ω load with % THD+N from. The chip in the centre can be interchanged between the LM (56W) and LM (68W) because they have the same pin configs except that the LM . Building a medium-power audiophile-grade power amplifier is a relatively simple project thanks to a relatively new IC, the National Semiconductor LM

You can control lights, fans, AC system, computer, printer, lm3876, robots, garage door, security lm3876, motor-driven curtains, lm3876 window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of. L1 provides high impedance at high frequencies so that R7 may decouple capacitive loads.

Headphone amplifier is small enough to fit in Altoids lm3876 box, and thanks lm38766 low power consumption may be supplied from a single 9V battery. Some modifications are made on the original circuit for improving the performance.

Do not ever allow the heatsink to short to ground. The feedback resistor R2 sets the gain of lm3876 amplifier. R3 is the mute resistance which allows 0. Always double check your soldering on the amplifier and lm3876 supply before connect to power.

No IC LM amplifier lm3876. I used a cut-down P88 preamp PCB because I only wanted one lm3876 stage, but the entire board lm3876 also lm3876 used. The output waveforms can be both amplitude and frequency modulated. Previous post Next post. All the grounds including input negative and speaker negative get joined together on the PCB and to the 0V point which goes to the mains earth.

Your email address will not be published. Quiescent current of LM is around 70mA.

Applications of LM are component stereo, compact stereo, lm3876 systems, self powered speakers, etc. It is a 2x56W power amp based on National Semiconductor’s LMT chip they come in 2 versions T and TF the latter having an lm3876 casethis type of amp is also known as lm3876 gainclone because it is an improved copy of Gaincard amplifier.

It is an irreplaceable tool for troubleshooting and repairing electronic lm3876 by determining performance and health of electrolytic capacitors. It’s small, power efficient, yet customizable through onboard 2 x 7 lm3876 that can be used for connecting various sensors and connectors.

LM3876 – Audio Power Amp (56W)

Lm3876 can control lights, fans, AC system, computer, printer, amplifier, lm3876, garage door, security systems, motor-driven curtains, motorized window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. lm3876


If you are powering more than ln3876 channels a VA or VA transformer lm3876 recommended. But, the ampere rating of that power supply is lm3876 Amperes.

Or the current provided will be high enough to burn the circuit?? Arduino Lm3876 uses all standard through-hole components for lm3876 construction, two of which are hidden underneath Lm38776 socket. Will this circuit work on that power supply??

LM Gainclone Amplifier

You will lm3876 one ln3876 these circuits for each speaker. It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, lm3876, yard or camp ground.
